How does Fredo care about his family when he witheld vital information from Michael about the senate hearings? Michael is not a psychopath, the people around him was inflicting his dark emotions. Think about it,
Connie: Doesn't respect Michael for killing her psycho husband who kills her brother (Sonny)
Fredo: Almost kills the whole family and witheld information to back Michael up
Kay: Aborts the baby
So who is truly loyal to Michael? Tom?..that's about it.
Look I love the godfather but characters like mike make me sick because they are murderers. Look Im not saying Fredo is a saint but he is much more humane than Mike is
